Abstract

An inductive component includes a core being formed of high-permeability MnZn ferrites having a secondary permeability maximum at a temperature <0° C. Electrically insulating material encapsulates the core.

Claims

exact text as granted — not AI-modified

We claim: 
     
       1. An inductive component, comprising: a core formed of MnZn ferrites having high magnetic permeability and a secondary permeability maximum at a temperature &lt;0°C.; and electricity insulating material encapsulating said core.   
     
     
       2. The inductive component according to claim 1, wherein said insulating material is plastic. 
     
     
       3. The inductive component according to claim 1, wherein said ferrites have an Fe 2  O 3  content in a range of 50 to 55 mol %, a MnO content of 15 to 35 mol %, and a ZnO content of 15 to 35 mol %. 
     
     
       4. The inductive component according to claim 1, wherein said ferrites have an Fe 2  O 3  content of 53.20 mol %, a MnO content of 24.80 mol %, and a ZnO content of 22.00 mol %.
